cascadeflow

cascadeflow is an open-source AI agent runtime layer that observes, scores, and steers agent execution steps to enforce policies and optimize model performance.

cascadeflow functions as an in-process runtime layer for AI agents, observing every model call, tool call, and handoff. It scores execution steps across cost, latency, quality, budget, compliance, and energy, then enforces policies using eight runtime actions. The software works with frameworks like LangChain, CrewAI, and PydanticAI, and supports providers including OpenAI, Anthropic, Groq, and Ollama. Studio provides visual builders for policies and domains, allowing teams to route queries to specialized model cascades and manage fleet-wide governance. It operates in-process, enabling granular control over decisions that gateways and proxies cannot access.
